Zane is a dangerous fellow who likes to go rock climbing in active volcanoes. one time, when he was
2020 meters below the edge of a volcano, he heard some rumbling, so he decided to climb up out of there as quickly as he could. he managed to climb up
44 meters each second and get out of the volcano safely.
graph the relationship between zane's elevation relative to the edge of the volcano (in meters) and time (in seconds).
answer: it is a positive linear association.
hope this !
£11.20 – £33
the minimum value in the table is £11.20. the maximum value in the table is £33. the range of costs is the interval bounded by these values.
the difference between the maximum and minimum is £33 -11.20 = £21.80.
"range" has two possible meanings here. when "range" is applied to function values, it has one meaning. when "range" is applied to statistical data, it can have a different meaning.the extent of function values, from the minimum to the maximum.the difference between the maximum and the minimum.
choose the meaning as defined in your curriculum material.
x = 7
given equation is :
14x-49 = x²
adding -x² to both sides of equation,we get
-x²+14x-49 = -x²+x²
-x²+14x+49 = 0
take -1 as common
-1(x²-14x-49) = 0
now multiplying above equation to -1, we get
x²-14x-49 = 0
now, above equation is in general equation.
split the middle term of above equation so that the product of two terms should be 49 and sum be -14.
x²-7x-7x-49 = 0
make two groups
x(x-7)-7(x-7) = 0
take (x-7) as common
(x-7)(x-7) = 0
now applying zero-product property to above equation,we get
x-7 = 0 or x-7 = 0
as both are same ,hence
x-7 = 0
adding 7 to both sides of above equation,we get
x-7+7 = 0+7
x+0 = 7
x = 7 which is the answer.
